The Ogwen Snack Bar is located at the western end of Llyn Ogwen and a good option for some post walk refreshments. It's open seven days per week for most of the year – opening only at weekends during the winter months. The popular snack bar can trace its history back to the early 1900’s when it was precariously perched on rocks at the head of the waterfall from which it takes its name. Known throughout the world it has its place in the mountaineering history in this part of Snowdonia and has been run by the same family since 1953. It moved to its current location over forty years ago to the newer premises incorporating Snowdonia National Park warden office and public toilets. It sells a range of drinks, snacks, pasties, paninis and locally baked cakes. There's an outdoor seating area where you can enjoy your food with fine views of the surrounding mountains. You can find the snack bar between Llyn Ogwen and Llyn Idwal at postcode of LL57 3LZ for your sat navs.
